Which of the following is the key step of the binary search algorithm
A
Each item is checked in order and moved based on the partition.
B
The sorted list is split into 2 and the middle point compared, then half is discarded.
C
The first 2 values are compared and swapped if necessary.
D
The unsorted list is split into 2 and the middle point compared, then half is discarded.
Explanation: 

Detailed explanation-1: -Binary search begins by comparing an element in the middle of the array with the target value. If the target value matches the element, its position in the array is returned. If the target value is less than the element, the search continues in the lower half of the array.

Detailed explanation-2: -Merge sort is one of the most efficient sorting algorithms. It works on the principle of Divide and Conquer based on the idea of breaking down a list into several sub-lists until each sublist consists of a single element and merging those sublists in a manner that results into a sorted list.

Detailed explanation-3: -This type of searching algorithm is used to find the position of a specific value contained in a sorted array.
